Hybrid tea rose plant named `Meizincaro`

ABSTRACT

A new and distinct variety of Hybrid Tea rose plant is provided which forms on an abundant and substantially continuous basis attractive fragrant double blossoms that are Cardinal Red in coloration. The plant exhibits bushy growth habit, glossy foliage, and excellent disease resistance. The new variety is particularly well suited for growing as attractive ornamentation in parks and gardens.

SUMMARY OF THE INVENTION

The new variety of Hybrid Tea rose plant (Rosa hybrida) was created byartificial pollination wherein two parents were crossed which previouslyhad been studied in the hope that they would contribute the desiredcharacteristics. The female parent (i.e., the seed parent) of the newvariety was the product of the cross of the `Meidaud` variety(non-patented in the United States). and the `Meisar` variety(non-patented in the United States). The male parent (i.e., the pollenparent) was the `Meinatac` variety (non-patented in the United States).The `Meinatac` variety sometimes is known as the `Susan Hampshire`variety. The parentage of the new variety can be summarized as follows:

    (`Meidaud`×`Meisar`)×`Meinatac`.

The seeds resulting from the above pollination were sown and smallplants were obtained which were physically and biologically differentfrom each other. Selective study resulted in the identification of asingle plant of the new variety.

It was found that the new variety of Hybrid Tea rose plant of thepresent invention possesses the following combination ofcharacteristics:

(a) forms on an abundant and substantially continuous basis attractivefragrant double blossoms that are Cardinal Red in coloration,

(b) exhibits a bushy growth habit, and

(c) is particularly well suited for growing as attractive ornamentationin the landscape.

The disease resistance of the new variety is excellent.

The new variety of the present invention can be readily distinguishedfrom its antecedent cultivars. For instance, the `Meidaud` variety formspink blossoms with no fragrance, the `Meisar` variety forms dark velvetyred blossoms, and the `Meinatac` variety forms pink blossoms and largerleaflets.

The new variety well meets the needs of the horticultural industry andcan be grown to advantage in parks and gardens where the brightlycolored blossoms contrast nicely with the glossy green foliage.

The new variety has been found to undergo asexual propagation in Franceby a number of routes, including budding, grafting, and cuttage. Asexualpropagation by the above-mentioned techniques in France has shown thatthe characteristics of the new variety are stable and are strictlytransmissible by such asexual propagation from one generation toanother.

The new variety has been named the `Meizincaro` variety.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph shows as nearly true as it is reasonablypossible to make the same, in a color illustration of this character,typical specimens of the plant parts of the new variety. The rose plantsof the new variety were two years of age and were observed during Junewhile budded on Rosa froebelli understock and growing in outdoors at LeCannet des Maures, Var, France. Dimensions in centimeters are indicatedat the bottom of the photograph.

DETAILED DESCRIPTION

The chart used in the identification of the colors is that of The RoyalHorticultural Society (R.H.S. Colour Chart). The description is based onthe observation of two year-old plants during June while budded on Rosafroebelli understock and growing outdoors at Le Cannet des Maures, Var,France. The coloration in common terms precedes reference to the chartin some instances. Such terminology is to be accorded its ordinarydictionary significance.
